Bute Inlet Hydroelectric Project

Alterra Power Corp., (formerly, Plutonic Power Corporation) is proposing to construct the largest cluster of hydroelectric projects ever built in British Columbia, on streams feeding into Bute Inlet. The company claims it will have a "nameplate" capacity of 1027 megawatts (MW) - 10% of the total hydroelectric generating capacity in BC Hydro's legacy dams - from 17 powerhouses.

The Project will be comprised of three interconnected groups of run-of-river hydro facilities on tributaries to rivers that drain to Bute Inlet on British Columbia’s central coast. In total, the three groups will be comprised of 17 run-of-river facilities, generating a total nameplate capacity of 1,027 MW. Six facilities (Southgate Group) will be located in the Southgate River Drainage, three facilities (Orford Group) in the Orford River Drainage, and eight facilities (Homathko Group) will be located in or near the Homathko River Drainage. Figure 1 illustrates the project location and general Project layout.

Each group of facilities will be connected to the proposed substation near the mouth of the Southgate River (referred to as the Pigeon Valley Collector Substation in figures associated with this document) through 216 km of 230 kV collector transmission lines on new right of way. From the proposed substation located near the mouth of the Southgate River, electricity will be transmitted 227 km through a 500 kV trunk transmission line to the point of interconnection with the British Columbia Transmission Corporation (BCTC) grid, at the BCTC Malaspina substation near Earls Cove.
